a person who rejects the mores of established society (as by dressing and behaving unconventionally) and indulges in exotic philosophizing and self-expression.

I believe code is my form of self-expression (I never said my self-expression was any good tho). Those that met me know I'm no hippy, altho I do have my fair collection of flashy shirts and hawaii boxer shorts.

I actually heard the word Beatnik in an episode of the Simpsons, back when I was a kid (must've been about 8 years ago). It sounded cool and I never heard of the beat-generation or Jack Kerouac before. The name stuck.
Before that I had a few silly aliasses on bulletin boards that probably died when Fido did :)
